微管相关蛋白tau是神经元缠结的主要成分,并且已被鉴定为阿尔茨海默病和其他tau蛋白病中的关键分子。然而,目前还不清楚主要位于轴突中的蛋白质如何参与被认为具有突触起源的疾病。为了研究tau可能的突触功能,我们研究了海马中的突触可塑性,并在体内和体外的tau基因敲除小鼠中发现了长期抑郁(LTD)的选择性缺陷,这种效应在体外通过RNAi敲除tau复制。我们发现LTD的诱导与糖原合成酶激酶-3介导的tau蛋白磷酸化有关。这些观察结果表明,tau在LTD中具有关键的生理功能。
The microtubule-associated protein tau is a principal component of neurofibrillary tangles, and has been identified as a key molecule in Alzheimer's disease and other tauopathies. However, it is unknown how a protein that is primarily located in axons is involved in a disease that is believed to have a synaptic origin. To investigate a possible synaptic function of tau, we studied synaptic plasticity in the hippocampus and found a selective deficit in long-term depression (LTD) in tau knockout mice in vivo and in vitro, an effect that was replicated by RNAi knockdown of tau in vitro. We found that the induction of LTD is associated with the glycogen synthase kinase-3-mediated phosphorylation of tau. These observations demonstrate that tau has a critical physiological function in LTD.
